Abstract
A multilayer ceramic capacitor includes: a multilayer structure in which each of a plurality of ceramic dielectric layers and each of a plurality of internal electrode layers are alternately stacked, the plurality of internal electrode layers being alternately exposed to a first edge face and a second edge face of the multilayer structure, wherein 1.5≤Db/Da≤10.0 is satisfied in a side margin region that covers edge portions to which the plurality of internal electrode layers extend toward two side faces other than the first edge face and the second edge face, when Da is an average grain diameter of a main component ceramic within 20 μm from an edge of the plurality of internal electrode layers in the side margin region and Db is an average grain diameter of a main component ceramic within 20 μm from a surface layer of the side margin region.
